Description

Technical Field

[0001] This utility model relates to the field of bathroom appliances, specifically to an anti-theft structure for a hand dryer. Background Technology

[0002] A hand dryer is a bathroom appliance used to dry hands. It comes in two types: automatic (sensor-operated) and manual. It is mainly used in hotels, restaurants, research institutions, hospitals, public entertainment venues, and home bathrooms. However, in public places with many people and observant individuals, hand dryers directly hung at bathroom entrances are easily stolen. Adding a lock to the hand dryer requires a key for disassembly and repair, which is inconvenient without one. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an anti-theft structure for hand dryers, which mainly solves the problem that traditional hand dryers use locks for anti-theft, which is very troublesome.

[0004] The technical solution of this utility model is as follows:

[0005] An anti-theft structure for a hand dryer includes a hand dryer housing and a mounting plate for fixing it to a mounting surface, and also includes...

[0006] A positioning slot is provided on the outer wall of the hand dryer housing on the side near the mounting surface;

[0007] An insert plate is disposed on the mounting plate, at least a portion of the insert plate extends into the positioning slot, and the insert plate is provided with a first positioning part;

[0008] A flexible pressure plate for manual unlocking is located inside the hand dryer housing. The pressure plate has a second positioning part that extends out of the hand dryer housing. The elasticity of the pressure plate causes the second positioning part to block and engage with the first positioning part, making the hand dryer housing impossible to pull out.

[0009] The first positioning part is a through groove provided on the insert plate, and the second positioning part is a boss provided on the pressure plate. At least part of the boss extends into the through groove and cooperates with the through groove to block it.

[0010] The boss includes a blocking surface and a ramp disposed opposite to the inner wall of the through groove. The ramp is used to slide and engage with the front end face of the insert plate when the insert plate is inserted.

[0011] The dryer housing is provided with a second through groove, and the positioning slot is connected to the second through groove.

[0012] The outer wall of the housing is provided with a guide groove, and the insert plate slides in conjunction with the guide groove.

[0013] The housing is provided with two second positioning slots, and the mounting plate is provided with a second insert plate that is arranged opposite to the second positioning slots.

[0014] The two second positioning slots are arranged at the three vertices of an equilateral triangle with the positioning slot.

[0015] The pressure plate is equipped with an operating section for manual operation.

[0016] It also includes a limiting plate, which is disposed on the inner wall of the positioning slot and gradually increases in height in the direction of insertion of the insert plate.

[0017] The beneficial effects of this utility model are: This utility model provides an anti-theft structure for a hand dryer, which can prevent theft, does not require a locking structure, has a low cost, and is suitable for installation in public places. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings: As shown in the figure, an anti-theft structure for a hand dryer includes a hand dryer housing 1 and a mounting plate 2 for fixing to a mounting surface, and also includes a positioning slot 11, which is disposed on the outer wall of the hand dryer housing near the mounting surface.

[0024] An insert plate 21 is disposed on the mounting plate, with at least a portion of the insert plate extending into the positioning slot. The insert plate is provided with a first positioning part 22. A spring-loaded pressure plate 3 for manual unlocking is disposed inside the hand dryer housing. The pressure plate is provided with a second positioning part 31 extending outside the hand dryer housing. The spring force of the pressure plate causes the second positioning part to engage with the first positioning part, preventing the hand dryer housing from being pulled out. During installation, the insert plate is inserted into the positioning slot (the positioning slot can be configured such that a crossbeam 10 is provided on the back of the hand dryer housing, forming the positioning slot between the crossbeam and the hand dryer housing). Under the action of the spring force of the pressure plate, the second positioning part will engage with the first positioning part to prevent it from being pulled out. When it needs to be removed, the hand dryer housing needs to be opened, and then the pressure plate can be moved back from inside the hand dryer to remove the hand dryer housing from the mounting plate. The mounting plate can be fixed to the mounting surface by screws, etc., and the mounting surface can be a wall or cabinet surface, etc.

[0025] In this embodiment, as shown in the figure, the first positioning part is a through groove provided on the insert plate, and the second positioning part is a boss provided on the pressure plate. At least part of the boss extends into the through groove and engages with the through groove. The insert plate is provided with a through groove. When the hand dryer housing is installed in place, the through groove will align with the second through groove on the hand dryer housing. At this time, under the action of elastic force, the boss will extend into the through groove to achieve a limit and prevent it from being pulled out.

[0026] In this embodiment, as shown in the figure, the boss includes a blocking surface 311 and a ramp 312 disposed opposite to the inner wall of the through groove. The ramp is used to slide and engage with the front end face of the insert plate when it is inserted. During the insertion process, the ramp engages with the insert plate and is subjected to force, causing the pressure plate to swing open. After it is in place, under the action of elastic force, the boss will fall into the through groove and be blocked by the blocking surface (preferably a plane) engaging with the inner wall of the through groove to prevent it from being pulled out backward.

[0027] In this embodiment, as shown in the figure, the hand dryer housing is provided with a second through groove 12, and the positioning slot is connected to the second through groove.

[0028] In this embodiment, as shown in the figure, the outer wall of the housing is provided with a guide groove 13, and the insert plate slides in conjunction with the guide groove. This facilitates guidance during installation and makes assembly easier.

[0029] In this embodiment, as shown in the figure, the housing is provided with two second positioning slots 14, and the mounting plate is provided with second insert plates 23 that are arranged opposite to the second positioning slots. The addition of two second positioning slots makes the entire assembly more stable after installation, preventing any shaking.

[0030] In this embodiment, as shown in the figure, the two second positioning slots are arranged at the three vertices of an equilateral triangle with the positioning slot. This structure makes the overall structure more stable.

[0031] In this embodiment, as shown in the figure, the pressure plate is provided with an operating part 34 for manual operation. This operating part can be an arc-shaped surface or a convex surface that increases friction, etc.

[0032] In this embodiment, as shown in the figure, a limiting plate 112 is also included, which is disposed on the inner wall of the positioning slot and gradually increases in height in the direction of insertion of the insert plate. The limiting plate can be a right-angled trapezoidal structure with its short side facing forward, and it will gradually tighten when the insert plate is inserted to prevent shaking.
